Outline
From Sediment to Rock
- Sediment
- small solid pieces of material
- water, wind, and ice
- carry sediment and deposit in layers
Erosion- Destructive forces
- breaking rocks on earth's surface
- forces
- heat
- cold
- rain
- ice
- waves
Deposition- water and wind
- deposits sediment
- sediments might include other things
- shells
- bones
- leaves
- stems
Compaction- over million years of compaction
- thick layers of sediment build
- compaction
- compacts sediment, squeezing them together
